=== Why is recently updated OpenCPN performing badly? ===

  - Look in the opencpn.log file. Try closing Opencpn, deleting the opencpn.log file and then reopening OpenCPN to create a new log file, then use Opencpn to cause the trouble again. Then look at the Log file to find messages that are associated with the problem.
  - Verify the problem is not from an old and outdated opencpn.ini file. Rename your opencpn.ini file for possible reuse later, and restart Opencpn to create a fresh new opencpn.ini file. Test for the problem.
  - Do you have Chart Display problems? Try turning on or off OpenGL and Running update of the Chart Database.
  - Do you have a problem with paid charts? see Oesenc or ocharts.
  - Do you have old plugins? Disable and uninstall all external plugins with the plugin uninstall program. Test OpenCPN and then download new updated plugins and install them one at a time and test.
  - Final Resort: Try starting over by uninstalling Opencpn following this approach.
      * Go to the ProgramFiles "OpenCPN" folder, and use the uninstall programs, preferably starting with the plugins, and ending with the OpenCPN.
      * Check that the "opencpn" initialization folder of program data has been removed. Otherwise, do it manually.
      * Use the CCleaner software to clean the PC Windows registry in particular. (option)
      * Download OpenCPN again and all the plugins you need.
      * Install OpenCPN.
      * Run OpenCPN to verify that the operation is correct.
      * Install, one by one, the plugins you need.
      * Run each plugin before installing another one
